采用真空蒸镀的方式制备了电致变色氧化钨薄膜,采用直流磁控溅射方法镀制了银层,采用电子束蒸发以插入层及共生的方式对氧化钨薄膜进行二氧化钛掺杂。使用UV757CRT紫外可见分光光度计测量了各样品随时间变化的透射率光谱。在CHI604C电化学工作站上进行了电化学测试,致色过程中进行了原位的光谱测量。使用原子力显微镜(AFM)和扫描电镜(SEM)观察了复合氧化钨薄膜的形貌。实验结果表明共生复合薄膜具有良好的环境稳定性,掺有银纳米层的复合薄膜与基底附着紧密,结构稳定,致色效率相对单层氧化钨薄膜平均提高了52.85%,漂白态和着色态的透射率差值达到了87.64%(λ=600nm,致色时间20s)。
The electrochromic tungsten oxide film was prepared by vacuum evaporation. The silver layer was plated by direct current magnetron sputtering. The tungsten oxide film was doped with titanium dioxide by electron beam evaporation and intercalation. The transmittance spectra of each sample as a function of time were measured using a UV757 CRT UV-Vis spectrophotometer. Electrochemical tests were performed on a CHI604C electrochemical workstation and in-situ spectral measurements were performed during the color development. Morphology of the composite tungsten oxide film was observed using atomic force microscopy (AFM) and scanning electron microscopy (SEM). The experimental results show that the composite film has good environmental stability. The composite film doped with silver nano-layer is closely attached to the substrate and has a stable structure. The average color rendering efficiency of the composite film is increased by 52.85% compared with that of the single-layer tungsten oxide film. Bleached and colored Transmittance difference reached 87.64% (λ = 600nm, induced color time 20s).
